This One Secret Can Double The Life Of Your Toyota Prius Hybrid Battery

There are many voices out there competing for your attention when it comes to fixing your hybrid battery. When we get right down to it, we should have learned how to take care of your Toyota Prius hybrid battery long ago. Learn why I am flying to Brazil to teach shop owners why this secret is so important.

If you have read any of my previous articles on hybrid batteries or hybrid battery repair, you already know how critical taking care of your hybrid battery is. The thing is, most consumers have no idea why their battery fails in the first place or what the symptoms are before failure.

We are taught that you drive your Prius, and if the battery fails, you have three options. Get it covered under warranty, replace it with a new or remanufactured one, or get a new car. The sad part is this, very few Prius owners get their battery covered under warranty. Once battery failure occurs, you only have two rather expensive options replacement of the battery or the car. Neither of which a hybrid owner wants to have to deal with.

What if there was a solution to this problem? What if we could double the expected life of our hybrid battery just by learning a few simple things about it? The good news is this is 100% possible, and it is available to Prius owners everywhere.

I am so passionate about hybrid battery maintenance that I am literally, as of this moment in writing flying down to Brazil. I have been asked to be a guest speaker at an automotive conference, my topic? Hybrid battery reconditioning and maintenance. Why? Because it is possible to keep your battery healthy for longer, and it is very affordable.

I want to give you some free knowledge here that I know will benefit every Prius owner on the planet. Then you can decide if it is right for you. Here is what you need to know about double the expected life of your hybrid battery.

What Causes Toyota Prius Hybrid Batteries To Fail?
First, we need to do some science here. Do not worry, there is no test on this, and I am going to give you all the answers you need. The science behind what makes our Prius go is the battery. The battery is made out of something called Nickel-Metal Hydride or for short NiMH.

Remember having an RC car as a kid? Then you probably remember Nickel Cadmium or NiCad batteries. I hated it when my truck only gave me 5 minutes of playtime after I charged it for hours on end. The thing was, I never knew what caused the issue, so I never knew how to correct it. The same thing happens with our Prius' and other hybrids.

Think about it like this. Visualize a bucket, in a river, filling with water. The water flows in the bucket, it fills up, and then the liquid flows out. If we were to go and pull the bucket from the river and pour it out, we would have, however, many gallons of water available to us from that bucket. Battery capacity is similar to this principle. In our hybrid batteries, we have a set level of capacity or storage that the individual cells can hold. If we start with a 5-gallon bucket, we have a lot of available capacity for use.

Now imagine that bucket staying in the river for years on end. What would happen? Believe it when I tell you that over time, that bucket would start to fill up with silt or debris that would begin to decrease the capacity or available storage of the bucket. It is the same idea as our Prius traction battery. This process is called voltage depression or crystal formation, and it is 100% going to happen. That is the bad news, battery failure is inevitable and will happen, it is just a matter of when.

Toyota Prius Voltage depsression

Luckily, we do not have to use NiCad batteries in our Prius, but we do have NiMH. This battery technology was hailed at the solution to the battery memory problem that plagued its predecessor. The thing was, the technology was still so new when Prius and Insight came out, we had no idea that we would be facing similar challenges with this new battery. Now all these years later, we are facing a memory effect. Now we know why our batteries are failing.

Ok, great, so every hybrid owner that has NiMH batteries is going to have a failure, thank you, Pete, I guess? You are darn tootin' you should be saying thanks because I am about to drop some seriously sweet knowledge on you about what can be done to postpone the problem for a much longer time.

The Secret The Dealers Do Not Want You To Know, Hybrid Battery Maintenance
Here is the secret that every Toyota dealer will never tell you about your NiMH hybrid battery. It is 100% serviceable. I know you are asking yourself the same question that I did when I was first learned about this concept. How do you service a hybrid battery? Does the Prius not maintain it by itself?

Excellent questions let us unpack this. When Prius and Insight first came out, there was not much data for these batteries over a long time. It was not until failures started occurring that people began to question why they were failing. Do you know why people began to question it? Because it cost a small fortune to have it replaced, that is why.

Toyota Prius battery modules

Prius and all other hybrids that are using NiMH have software built into the BCM (battery Control Module) that only allows the battery to cycle anywhere from 20 to 80 percent state of charge. In doing so, this keeps the battery chemistry happy, and we can see a longer life out of it. The bad news is that it causes voltage depressions or "silt in the bucket."

Okay, I get it, silt in the bucket, so now what? We get a reconditioned battery and drive the car. Yeah, you can do that, but ask yourself this question. What if you did not have to replace the battery for even longer than expected? Would that not be worth looking into? Of course, it would.

This is precisely what drove the owner of Hybrid Automotive to find a solution that is giving Prius, Insight, and other hybrid owners freedom from battery replacement. He did the hard work, figuring out how. How batteries fail, and what can be done to repair and maintain them. He took what the repair companies were doing and packaged it in a ridiculously simple package that any hybrid owner can use. It is the Prolong Hybrid Battery Reconditioning package only available through Hybrid Automotive.

How Can The Prolong System Help My Prius?
Excellent question. Let me ask you one first. How long do you expect you will own your Prius? Five years, ten years, longer? If you want to own a Prius, you need this tool.

The complete system is an easy install of a wiring harness and a weekend recondition on your battery two times a year. The system, once installed, works with your aging battery to help remove the crystal formation/voltage depressions and restore lost capacity.

Remember the bucket? What if you could dip your hand in the bucket and clear out the silt? Would you then have more room for water? Heck, yes, you would. So, what if periodically you went in and kept clearing out as much silt as you could from the bucket? Do you think you would have more available capacity at the time you need it most? Of course, you would.

This system does just that, and it is incredibly affordable. The whole system is less than half the cost of a remanufactured hybrid battery for your Prius. You are welcome. I just saved you thousands of dollars over the lifetime of your Prius.

Where Can I Get This System For My Toyota Prius?
If you are interested in learning more about this product, please let me know. Find me on social media, send me an email, I will gladly explain anything unclear to you about how this system can take care of your Prius or other hybrid vehicles.

If you have seen the value already and want to get started, take a look here that will ensure you will get a kit that fits your Prius.

Key Take Away From Today
Hybrids like our Toyota Prius' that use NiMH will get a memory effect; it will happen. When your battery fails, it will be expensive, and no just replacing one module is not a lasting repair, it is a band-aid best. The pack will be unbalanced, and you will be out more time and more money. Both of which no one wants.

Ask yourself these questions, though. If all this product did was help you maintain peak battery performance, would it be worth it? If all that happened was that you doubled the expected life on your hybrid battery, would it be worth it? Of course, it would be. We both see the value in it. We both know it is worth the relatively small investment that will pay for itself within the first time you use it.

You can slow the voltage depressions drastically by using the Prolong kit from Hybrid Automotive. It is proven to recover and restore capacity in your hybrid battery. Some batteries are not great candidates for reconditioning, but if your Prius has not failed yet, you are an even better candidate. Preventative maintenance will, for sure, keep your battery running longer and give you many more miles of trouble-free driving.

Again, feel free to reach out to me if you have questions, I am more than happy to help any Prius or hybrid owner get the most out of their car. I own two hybrids myself and have the kit installed on them. I am entering a long term study with a 2nd generation Prius to see how long I can keep the original battery in service. It is going to be exciting.

Thank you so much for reading. This is a long but necessary story. I do it because more hybrid owners need this product. We need to maintain our battery on our cars, and we need to keep them on the road longer.

The "miracle" system referred to in this article does nothing more than an ordinary iMax modeling charger. When you buy a "30" times more expensive system, you pay for convenience> We do not have to handle each module separately, we save a lot of time in relation to the individual regeneration of each module. The question is how much time we want to spend and how much money we spend. 10-50$ iMax charger vs 1000$ Prologis system?

The iMax modeling charger is not even close to being the Hybrid Automotive one. Those modeling chargers can't charge at low current and aren't useful for hybrid battery reconditioning. Everything looks good and working until the so-called reconditioned battery is installed on car and used with a 100 amp charge-discharge.
Since 2020 I've successfully rebuilt and reconditioned dozens of Toyota hybrid batteries with Hybrid Automotive charger.
Until 2020 i've played around with modeling chargers, wasting my time until i got stuck with 2 batteries that were throwing P0A80 code.
The Hybrid Automotive charger uses Chinese voltmeters which lie, initially at a few volts and now at 30 volts after a few years of use. The charger shows 240 volts, but in fact 230 or less. I think this is the number one reason why customers have not been able to restore their batteries with this charger.

I have a 2001 Prius where I replaced all the cells with Gen 2 cells some time back. 2 years ago I replaced 4 cells that had low voltage. Couple of months ago I replaced 2 more. I just now plugged in a Veepeak OBD device and loaded Dr. Prius app on my phone. The graph is all over the place, up, down, back and forth, green bars, yellow bars. Is there a device that can balance out the pairs? I'm thinking of converting to Lithium but expensive.

Thanks for the article... Just wondering if this device can be used on Li-On battery on 2017 Prius Two Eco. Thanks in advance...

My original hybrid in Prius 3rd. gen. is charging up to 100% day by day. It happened more often on dashboard in icon… more than 15 times. I am very worried! What should I do? I only replaced 12V battery at the dealership over 2 years ago and fixed defective piston rings

A disappointing article. The excess verbiage and self-congratulatory tone combined with minimal information leaves me suspicious. Not a good look for TorqueNews.

Hello Peter, I have a Toyota Prius 2012 Plugin Hybrid. I am not really sure if it has NiMH battery only or a Lithium plus NiMH. Currently, the battery only charges enough to give 8.6 miles but it is supposed to be around 15 on a full charge. The car is on 192k miles. Can you please advise what can be done if possible?

Thank You!

I'm second owner 2006 Escape hybrid with 167k and I am retired collision repair tech Sun Toyota New Port Richey FL. Bought the escape when retired NW Arkansas nearest Walmart 42mi.The early Prius after a collision repair that state of charge was low enough to no start service would charge then drive in reverse until completely dead and recharge/drive to take the top charge from jumpstarts off and only charge 47%. I've done this once a year with my Escape then trickle charged through relay box just until pack starts gas motor with no idle or dash lights usually 4hrs then drive 100miles my pack runs 62-67% soc 360volts all packs self test ok getting data stream from forscan I've never reset start date or used the forscan rebalance service. I'm convinced that battery failure has nothing at all to do with the start date or memory the battery is at its max state of charge when purchased then transported dealer to sit for dealer prep then detail then on lot for months then purchased the full charge when left the factory is the only full charge memory the battery ever needs period the service start date does not do anything to fail the battery and cells fail from topping off maintenance charging the pack and creating dead spot between top and bottom of cells closest to the charge input I'm going start changing the order of my cells then drain dead reverse charge drive and save my money no thanks

Hi.

I am new to repairing Prius batteries and would like to learn more about reconditioning a battery and equipment needed for it and where to buy it. I would appreciate it if you could please tell me where can I find DIY videos so I can understand better.

Jore (not verified)    September 21, 2022 - 4:24PM

New Prius battery ~$3,500. Buy a new one and forget the $2K for battery reconditioning. If anyone knows anything about rechargeable battery’s you recondition them by fully draining them then recharging them and then repeating several times. I’ll bite the bullet and buy a new battery.

Carol J Wilson (not verified)    January 14, 2023 - 3:22PM

My car is in the dealership now and I am told it needs a new battery..I am checking out the dealer and deciding whether to get it repaired. If I get new battery I would be interested for my 2008 Prius with 115,101 miles.
